Our Story
Our roots go back to 1946, when Elmer Earl Koen founded Koen Tile Company. After Elmer died, his son Donald and Donald's wife Pamela carried the family business on. They ran the tile company together before moving into plumbing in 2000, and that is the company you call today.
Their oldest son, John Koen, became our Responsible Master Plumber, and much of our name for careful workmanship was built on his watch. The family lost Donald in August 2014, John in April 2022 and Pamela in November 2022. Their legacy is still the thing this company runs on.
Koen Plumbing is owned and run today by three people. John's wife Heather Koen is President. His sister Sarah Koen is Secretary. Salvador Gomez, a longtime friend and colleague of John's, is Vice President and our Responsible Master Plumber. We became Koen Plumbing, Inc. in 2012, and we've been accredited by the Better Business Bureau since 1981, with an A+ rating.
The Crew Customers Ask For
Our customers tend to remember who came to their house. Mario, Salvador, Alfonso and Omar come up by name in our reviews. Customers mention them for turning up when they said they would and for taking the time to explain the job. When you call, you'll get someone from the same crew.
How We Work
When you call 972-406-8076, a person in our office answers and books a time with you. There's no charge for us to come out and look, anywhere in our service area. Your plumber explains what's wrong and gives you the price in writing, and nothing starts until you say yes. We show up at the time we gave you, and when the job is done we leave the area the way we found it.
What Our Neighbors Say
We have 4.9 stars from 86 Google reviews. Richardson Life Magazine readers voted us Best of Richardson 2026, and our neighbors on Nextdoor made us a 2026 Fave Winner. Some customers have used us for more than 15 years, and one told us it's been 40. Plenty of our customers found us through a neighbor or a friend, and we like it that way.
